Like them or not, here are a few:
All they that take the sword, shall perish with the sword.
The Bible
Matthew
All war represents a failure of diplomacy.
Tony Benn

Dwight D. Eisenhower
Never think that war, no matter how necessary, nor how justified, is not a crime. Ask the infantry and ask the dead.
Ernest Hemingway
They wrote in the old days that it is sweet and fitting to die for one's country. But in modern war, there is nothing sweet nor fitting in your dying. You will die like a dog for no good reason.
Ernest Hemmingway

Dwight D. Eisenhower
